COMBINED LISTER AND DRILL.

SPECIFICATION forming part of Letters Patent No. 422,603, dated March 4, 1890.

Application filed April 2, 1889. Serial No. 305,726. (No model.)

To aZZ whom it maycpncern:

Be it known that I, WILLIAM A. LOUGHRY, of Odessa, in the county of Bufialo and State of Nebraska, have invented a new and 1111- proved Combined Lister and Drill, of which the following is a full, clear, and exact description.

The invention relates to combined listers' and drills such as shown and described in the application for Letters Patent filed by me September 5, 1888, Serial No. 284,647.

The object 'of the invention is to provide certain new and useful improvements in a combined lister and drill, whereby any desired amount of soil can be turned onto the seed in the center of the trench formed by theplow.

The invention consists of'certain parts and details and combinations of the same, as will be fully described hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification,- in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is aside elevation of the improvement. Fig. 2 is an end elevation of the same. Fig. 3 is a plan view of the same with parts broken out. Fig. i is an enlarged sectional side elevation of the seed-box. Fig. 5 is a transverse section of the same. Fig. 6 is an enlarged transverse section of a disk and its support, and Fig. 7 is an enlarged sectional side elevation of the diskeholder.

The combined lister and drill is provided with a plow A, on which are secured the .moldboards 13, and to the latter and the plow A is fastened the plow-beam 0, extending to the front and carrying at the outer end the usual clevis D,,carrying the whiffietree to which the horses are attached. On the plow O is pivoted at E the curved bar E, carrying at its lowest point a Wheel F, traveling on the ground in front of the plow A, and serving to regulate the depth of the trench formed by the plow. The front end of the barEis provided with a number of apertures E through one of which passes a pin E also passing through a corresponding aperture in the front endof the plow beam C. When the pin E is removed, the bar E can be raised or lowered to any desired height, so as to adjust the wheel F. The pin F. is then inserted through the corresponding aperture E registering with the aperture in the beam.

Near the rear end of the beam 0 is pivoted, at H, a frame H, extending rearward and carrying at its rear end a shaft 1, on which is secured a grooved wheel J, held in line with the plow A. On the shaft I is also secured a sprocket-wheel I, over which passes a sprocket-chaiu 1 also passing over a sprocket-wheel 1 secured on a shaft K mounted to turn in suitable bearings in the. upper end of the frame H, which at this point carries the seedbox L. (See Figs. 4; and 5.) On the shaft K is secured the seed dropping wheel K, provided with recesses K in its periphery, said recesses being adapted to register with an aperture L, formed in the bottom-of the seedbOX L.

' The seed-dropping wheel K is mounted to turn in a-suitable recess in the bottom of the seedbox'L, and is adapted to discharge into the spout N, extending downward between the mold-boards B to discharge into the center of the trench formed by the plowA. The latter may be provided at its rear end with a small ridger or subsoiler A, extending below the plow, so as to form a small furrow, into which the seed is dropped from the spout N. The latter is provided at its upper end with hooks N,.hooking into aperturcd lugs N secured to the frame H.

On the pivoted frame H, between the grooved'whe'el J and the seed-box L, are secured on each side angle irons 0, each of which has its part 0 provided with slots, through which pass bolts securing the angleirons to the frame H. The slots in the parts 0 permit of a longitudinal adjustment of the angle-irons. The other arm 0 of each angleiron extends at right angles to the frame H, and on it is mounted to slide a holder P, in which screws the setscrew P for securing the holder at any desired point on the arm 0 A vertical slot is formed in the holder P, and through it passes arod Q, adapted to be turned in the said holder and raised or lowered to any desired height and then fastened in place be turned in the holder P, any desired position may be given to the said concave disks R. The grooved wheel J, following directly behind the disks R, serves to tamp and give an oval form to the ridge in the bottom of the trench formed by the disks R.

The rear end of the frame H is pivotally connected with the upwardly-extending rod. S, which extends between the plow-handles G, secured in the usual manner to the moldboards B. On the upper end of the rod S is formed a handle S", by which the operator can conveniently raise or lower said rod S, thereby causing an upward or downward swinging motion of the frame H and a lifting of the grooved wheel J and the disks R whenever desired. On the rod S is secured a hook S adapted to be thrown over a transverse rod G, secured to the handles G. hen the operator lifts the rod S upward, as before described, he can hook the hook S over the rod G, so as to hold the wheel .J and the disks R in an elevated position.

Next to the fixed handle S is pivoted a spring lever T, pivotally connected by the link T with a scraper U, fulcrumed on the rod S and resting in the periphery of the wheel J, so as to scrape off any dirt gathering on the periphery of the said grooved wheel J.

The operation is as follows: When the iinprovement is drawn forward in the direction of the arrow a, the plow A, with the small plow A, forms a trench into which the seed 1 is discharged from the seed-box L. The seed dropping wheel K in theisaid seed-box is operated from the wheel J, so that seed is regularly dropped at suitable intervals. The disks R, following directly behind the plow A, form a ridge over the seed in the trench. The grooved wheel J in the rearof the disks R tamps the ridge and gives it an oval form,

so that the seed planted in the trench will readily germinate in the dry season, and at the same time prevents an early germination of the weed-seeds. The form of the ridge in the bottom of the trench also allows an earlier cultivation of the corn, &c., by the use of the harrow or cultivator than can be obtained by other forms of listers and drills now in use. It will further be seen that the soil thrown over by the plow buries the surface between the trenches without any break or thin spot to allow the early germination of weed-seeds.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1. A drill attachment for plows, comprising a frame adapted to be pivoted to a plow-beam, a grooved wheel mounted in the rear end of the frame, a hopper on the upper end of the frame, a seed-dropping wheel journaled in the frame below the hopper, a seed-spout below the wheel, angle-bars adjustably secured to the frame, concave disks adj ustabl y secured to the bars, a bar pivoted to the rear of the frame and adapted to engage the round of the plow-handles, and means for operating the seed-droppin g wheel from the grooved wheel, substantially as herein shown and described.

2. A drill attachment for plows, consisting of the frame H, the grooved wheel J, j ournaled in the lower end of the frame and provided with the sprocket wheel I on the endof its shaft, the dropping-wheel K, journaled in the upper end of the frame and provided with. the sprocket-wheel I on the end of its shaft, the chain I passing over the said sprocket-wheels, the hopper L above the droppin -wheel, the

spout N below the said dropping-wheel, the

slotted angle-irons 0, adjustably secured to the opposite sides of the frame, the holders P, adjustably secured to the angle-irons, the standards Q, adj ustably secured in the holders, and the disks mounted on the lower ends of the standards, substantially as herein shown and described.
